Summary
We developed a novel hybrid material combining covalent organic frameworks (COF) and metal-organic frameworks (MOF). This COF/Mn-MOF hybrid demonstrates excellent lithium-storage performance due to its unique structure and activated manganese centers.
Area of Science:
- Materials Science
- Nanotechnology
- Electrochemistry
Background:
- Covalent organic frameworks (COF) and metal-organic frameworks (MOF) offer tunable properties for diverse applications.
- Controlling pore size and composition is key to optimizing material performance.
- Hybrid materials can combine the advantages of different framework types.
Purpose of the Study:
- To synthesize and characterize a novel coordination-induced hybrid of COF and Mn-based MOF (COF/Mn-MOF).
- To investigate the lithium-storage performance of the developed COF/Mn-MOF hybrid.
- To explore the potential of COF-MOF hybridization for advanced materials design.
Main Methods:
- Coordination-induced synthesis of COF/Mn-MOF hybrid materials.
- Characterization of the hybrid's morphology, structure, and composition.
- Electrochemical testing for lithium-ion storage evaluation.
Main Results:
- The COF/Mn-MOF hybrid exhibits a unique flower-like microsphere morphology.
- The hybrid demonstrates superior lithium-storage performance attributed to activated Mn centers and aromatic benzene rings.
- Derived MnS@NS-C materials also show promising lithium-storage properties.
Conclusions:
- The molecular-level compositing of COF and MOF creates a hybrid with enhanced properties.
- This COF-MOF hybridization strategy offers a pathway for designing advanced porous materials.
- The developed materials show potential for high-performance energy storage applications.

26.4K
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).
